sAsH-FAsTENER.

SPECIFICATION forming part of Letters Patent No. 619,461, dated February 14, 1899. Application led August 18,1898. Serial No. 688,878. (No model.)

To all whom t may concern:

Be itknown that I, MYRON ANGEL, a citizen of the United States, residing at San Luis Obispo, county of San Luis Obispo, State of California, have invented an Improve ment in Door and Window Locks; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to a device for securing doors and window-sashcs and making them absolutely tight in their frames, with means whereby they can be instantly looscned, so as to be opened or moved, and in the case of sashes they may be again locked firmly at any desired point.

It consists in details of construction which will be more fully explained by reference to the accompanying drawings, in which- Figure 1 is a front view of a window with my attachment at side and top. Fig. 2 is an edge view of the same. Fig. 3 shows a door with my lock fixed to side and bottom.

Doors and windows, however accurately fitted at first, soon become loose by shrinkage, and when in this condition they rattle and also allow cold air, dust, or rain to enter.

In car-windows it is especially desirable to have the windows loose for the purpose of allowing them to be raised or lowered easily; but when closed it is necessary that they should be absolutely tight to prevent the ingress of dust and to prevent rattling. In the ordinary construction, however, they are made so tight for the purpose of excluding dust that it is frequently impossible to-move them at all. My invention is designed to give the utmost freedom of movement when it is desired to move the window and to afterward lock it, so as to make it absolutely immovable and dust and rain tight.

In Figs. l and 2 I have illustrated my invention as applied to a vertically-sliding window-sash A, which is movable in the sash guides or channels for the purpose. The edge of the sash has a groove or channel cut in it, and within this groove or channel are fitted the strips O and O. The meeting faces of these strips are formed with diagonal inclined surfaces with intervening offsets at approximately right angles therewith, forming upon each strip a series of inclines extending from one end to the other. These offsets lying against each other, the outer edges of the strips will stand approximately parallel with each other, and when the strips are thusA placed together and introduced into the grooves or channels in the edge of the sash the outer edge of the outermost strip lies approximately flush with the edge of the sash and the strips extend the full length of the side in which they are fitted.

The outer edge of the'strip C is preferably covered with a strip of rubber, felt, or other material which will resist the entrance of air,

dust, or water.

The innermost strip O may have a toothed section E formed or let into it ata convenient point, and this is engaged by a pinion F, fixed to a shaft extending transversely through the sash adjacent to the groove or channel in which the strips lie. The outer end of this shaft has a head G, by which it may be turned, and when it is thus turned it rotates the pinion F, and this engaging With the toothed rack E will advance the strip upon which the rack is fixed. This strip is shorter than the channel in the direction in which it is to be advanced, and the outer strip abuts at each end against a stop H, which prevents its moving longitudinally. Vhen, therefore, the inner strip is thus moved with relation to the outer one, the inclined faces advance over the corresponding inclined faces of the outer strip, and thus force the outer strip outwardly and cause it to bind firmly against the side of the frame, in which it is slidable. Thus when the windowis closed strips of this side may be fitted in one edge, and the opposite edge of the sash may, if desired, have a flexible strip C2 fixed to it to make a joint upon that side.

Whenv the window is closed, by turning the actuating-knob the strips O C are forced apart and the outer one is forced strongly against the inner face of the guide or casing upon that side, thus binding the sash firmly, preventing its rattling or being opened, and thoroughly excluding dust. If there are two sashes, as in ordinary windows, a similar arrangement of slidable strips is fitted into the top rail of the lower sash, and in this case the inner strip may be movable by a slidable pin or knob I, and this device may also be used in place of the rack and pinion, if desired,

IOO

the operation being essentially the same as when operated by a pinion and rack. In either case the strips are forced apart on account of the inclines and the outer strip will bind against the lower edge of the upper sash, thus making a tight joint along the meeting edges. As the inolines extend the full length of the sashes wherever they are fitted, it will be manifest that the whole length of the strip will be forced out simultaneously and a joint will be formed from end to end. The same construction when applied to the edge of a door will form a joint at that edge, and the vertical and horizontal edges can also be litted with these slidable strips, so as to form joints at the edge and at the bottom of the door, as shown in Fig. 3, the latter being especially useful to keep ont wind and rain when the door is closed.

By connecting the vertically-movable strip with the horizontally-movable one a single knob or slide will operate both. This connection may be made by beveling the meeting ends of the strips C, as shown at J, so that the employment of one will act upon the other, or a connection may be made by means of a bell-crank lever, which will produce the same result.

K K are springs acting upon pins fixed in the strips C', so that when these strips are relieved from the outward pressure of the strips C the springs will retract the strips C and allow the connected parts to move easily. The pins pass through slots in the strips C and pass through plates a and enter sockets or openings in the sash, and on the inner ends of these pins the springs are placed.

When applied to a door, as shown in Fig. 3, the lower end of the vertical strip C acts when it is forced down to move the corresponding horizontal strip, and both act simultaneously upontheirrespectivelocking-strips C. Vhen the vertical strip C is retracted, the horizontal strip will be returned to its normal position by the springL, and the retracting-springs K are then free to retract the strips C', as previously described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination with a door or window, of slidable strips disposed in pairs and having their contacting edges formed or provided with inclined surfaces, means whereby one strip is held against movement lengthwise, a toothed section on the other strip and a pinion engaging the same for operating the movable strip, pins fixed to the stationary strips and extending through slots in the other strip and springs on said pins and adapted to retract the stationary strips and allow both strips to move in unison.

2. The combination with a window or door, of strips sliding in channels made longitudinally from end to end in the edges of the door or sash, said strips being disposed in their respective channels in pairs, and having the contacting edges formed with a series of inclines extending from end to end, means whereby one of the strips is held stationary and mechanism by which the other is movable longitudinally with relation thereto whereby the movement in one direction loosens the outer strip and allows the sash or door to move freely and movement in the opposite direction locks the outer strip against the casing to form a tight joint and prevents movement,

and means whereby the adjacent ends of strips movable at right angles with each other are connected so that the movement of a horizontal strip is transmitted to and operates a vertical strip.

In witness whereof I have hereunto set my hand.

MYRON ANGEL. Witnesses:
